In this paper, the influence of fillers like molybdenum disulphide (MoS2) and nanoparticles in polyamides describing friction and wear behaviour was investigated. Reciprocating wear experiments were performed in polyamide 6 (PA6) and polyamide 6.6 (PA6.6) against low carbon steel counter plates using a medium scale flat on flat tribotester. The polymer test specimens were slid at a constant velocity of 10 mm/s and contact pressure of 10 MPa was included. The experimental results demonstrates that the friction coefficient of PA6 increase with increasing the temperature caused by frictional heating. PA6.6 composite filled with molybdenum disulphide (MoS2) has lower coefficient of friction on comparing with PA6 due to the addition of nanoparticles. The PA6.6 sliding against steel is found to be more sensitive than PA6 to stick-slip motion, which complicates the wear mechanisms involved.. }
